Another Barney Question

I have been told that the Logans Ridge track can be accessed from Yellow Pinch carpark without going all the way back along Upper Logan Rd. This would remove a boring section of the hike and also the need to go through private property which is clearly signed NO TRESPASSING. It would make more sense to do the entire walk on NP property. Has anyone taken this route and if so, info would be appreciated. I recently did Logans again for my 72nd birthday and it is one of my all time favourite walks but didn’t want to spend time trying to find a new route myself as I had other family members with me who were doing the walk for the first time and couldn’t risk wasting time before we had even started.
Thanks
John
